GOWER Hose,

My invention relates to shingles used for roofing and the like and has for some o f its principal objects, to provide a composition shingle which when laid in place shall present a more pleasing and attractlve appearance than is presented by those formsof composition shingle hitherto employed which lack a thickened or butt end, and which shall also be capable of interlocking, one with another, so as to provide a more or less close approach to a roof of unitary construction, at the same time leaving sufiicient freedom between the separate interlocking parts to permit of expansion and contraction and a certain amount of flexibility. Other objects of my invention and some of the advantages thereof will be hereinafter set forth.

The invention consists in the novel con-- arrangement and combination of struction, various elements and parts, as defined in the claims, some of the embodiments of the said invention being shown in the accompanying drawings and particularly described in this specification.

In the said drawings Fig. 1 is a perspective view of a building provided with a roof employing one formof my invention; Fig. 2

is a sectional view of a portion of such a roof; Fig. 3 is an enlarged perspective view of a small portion of such a roof, showing more clearly the particular manner in which .the sections of roofing, or strip shingles, are

placed in juxtaposition and interlocked;

Fig. 4 is a plan view of a single four-shingle strip of the form of roofing shown in Fig. 1, and Fig. 5 is a view of the same folded ready for interlocking with neighboring strips; Fig. 6 and Fig. 7 are similar sectional views but showing a modlfication of this form of the invention.

The general inventive idea set forth in this application comprises a composition roofing shingle, made either singly or in a strip comprising several shingles, said shingles or said strip being folded in .such a way as to interlock with adjacent shingles or strips, and

and a resident the folds being so arrangedas to form a butt end or edge in the lower portion of each shingle or strip, thus producing the pleasing appearance which is desired in roofs of this character, which is dependent upon the breaking up of the fiat expanse of roof by a series of steps or edges such as are presented-by the butt end of an ordmary wooden shingle.

The invention, as shown in the embodi-' ment ofFigs. 1 to 5 inclusive comprises a shingle composed of a composition roofing material comprising a body 20 having a downward extension 21 and an upward extension 22. The lower edge of the extension 21 is underfolded forming a flap having a hooked flange 28. The upward extension 22- is overfolded onto the body 20 as shown in Fig. 5. The shingle in its preferred form comprises an elongated body orstrip 20 having a series of multiple shingles or shinglemembers, preferably four in number, the strip being provided in its lower edge with a series of slots 26, which form the individual downward extensions 21 with recesses between them, and give the appearance when the strip is folded and placed upon the roof of separate shingles. The

strip is also provided at its upper edge with another series of slots 27 disposed opposite said extensions and between the slots or recesses 26 of the lower edge, said slots 27 registering with the slots or recesses 26 of a superposedstrip or shingle. At the two lower corners of each strip, small portions are cut away as shown at 50 in Figs. 4 and 5, each of these cut-away portions corresponding to one half the width of a slot 26. Thestrip shown in-Fig. 4 is bent into the form shown in Fig. 5, creating a preformed lower underfolded flap having a hooked flange .28 and an overfolded flap- 29.which overlies the body 20. The strip is then ready for laying on the roof. The strips are laid,

beginningI inthe usual manner at the lower part of e roof, and each strip is fastened to the roof by one or more nails at some convenient point in the body 20 underneath the overflap 29. A second strip is then applied, the hooked flange 28, of the underfiap being inserted under the overflap 29 of the preceding or already attached strip, forming afree connect-ion between them; and the second strip is then suit-ably secured to the roof by one or more nails. The manner in which the strips are applied together and interlocked will be clearly seen from the enlarged perspective view Fig. 3. It will be seen that each strip is not applied directly over the preceding strip, but is shifted a little to one side or the otherin the drawings the strips are shown shifted slightly to the right this being for the purpose of bringing the slots 27 in the overlying flap 29 into register with the slots 26 of the previously laid strip and at the same time bringing the edges of each successively laid strip out of register with the edges of the previously laid strip,

in order that there may be always the protection of a plurality of layers of material over the roof at every point as will be seen by an examination of Fig. 3, which could not be the case if the strips were laid one directlyover the other. The general appearance of acompleted roof constructed according to,

this embodiment of my invention, is shown in Fig. 1, the extreme upper left-hand corner, however, being left uncompleted to show the appearance of the roof when it still lacks the completing rows of shingles.

Another form of interlocking is shown on a larger scale in the sectional view Fig. 6, and in Fig. 7 I show still another modification of this construction and of the manner of interlocking the same. In F i 7 I show a form provided with an underfolded flap 28 as before, but I dispense with the come paratively long overfold'ed flap 29 and instead provide a comparatively small separate piece of material 35 which is placed in about the same position as would be occupied by the lower edge of the said overfolded flap, and is there secured by means of nails 36; this piece 35 forms a member with which the lower or underfolded flap 28 of the next succeedin shingle may be interlocked. In Fig. 7 show a similar sectional View of a form provided with the underfolded flap 28 as before, but with a doubled or pleated form of upper interlocking member 37 instead of the previously described form of overfolded flap, with which the lower or underfolded flap 28 of the next succeeding shingle may be interlocked.

It will be noted that in the forms of shingle which I hav above described and shown in the accompanying drawings I provlde a devlce which can be cut from a roll of roofing mater al with a minlmum of waste and which can be prepared for folding and placing upon the roof in connection with other elements in an expeditious manner, and that the said elements may be easily and quickly interlocked together, forming a securely united complete structure, which affords complete protection at every point against weather conditions. It will also be seen that the interlocking, while. efiicient and practically permanent, is not rigid, but provides a sufii'cient amount of" freedom and play to render a roof struct constructed acoor to any of the traction under weather conditions, thus preventing wrinkling, warping or curling of the roof or any of its component parts. The strips, or separate shingles as the case may be, may be cut from rolls, large strips or other pieces of material in the already well understood manner, or may be formed in any suitable way. The material may be any suitable form of roofing material which may be desired, and either covered with crushed slate, stone or the like, or treated in any desired way, so that my invention possesses a high degree of adaptability and is well suited for practical commercial use in the art.

It will of course be understood that in laying a roof composed of strips or shingles such as I have above described the separateparts may be secured by nails or otherwise in the accustomed manner as far as may be necessary to properly retain the same in posuiiiciently to produce a united structure adapted to produce thefiresults required in roofing structures.

In describing my'invention in this specification I have alluded to the same as being a roofing structure and as being laid upon or as a component part of a roof. It should, however, be understood that the use of structures such as I have described is not limited to the roof of a building. It is well known in the art at the present time to cover the side walls of buildings or a portion of said walls, with shingles'or similar structures, and it is obvious that all of the forms or embodiments of my invention which have been described, as well as other embodiments of which the same is capable, may be employed to cover any portion of a building or similar structure upon which the same can be advantageously used.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:

1. The combination of a plurality of self interlocking shingles re spectively comprising bodies composed of composition roofing and having downward extensions forming intervening recesses and also having overfolded upper portions fprovidedwith slots registering with the slots or recesses of the downward extensions of the superposed shingles.
